Title: if you don't know
Post by: navi on July 13, 2018, 08:47:50 am
Are these sentences correct:
1) Do not reply to this question if you don't know.

I think it has to be 'if you don't know the answer' or 'if you are not sure'.

Gratefully,

I depends what the question is.
Seems an odd statement though how could you reply to a question if you don't know?

Thank you very much, Darryl,

I see your point. I just wanted to know if 'know' could be used that way.

Would you say these work:

2) I can't answer a question if I don't know.
3) I can't answer a question if I don't know the answer.
4) I won't answer a question if I am not sure.

My problem with '2' is that it doesn't seem clear what I am supposed to know.


Gratefully,
Navi

Yes, they work.
You don't really need 'the answer' in #2 as that is understood.
